When hitting the download pages for Workstation, Server and Cloud > Docker, the link to the Release Notes (http://docs.fedoraproject.org/release-notes), is pointing to the F21 Documentation > Release Notes.
Example: https://getfedora.org/en/cloud/download/download-cloud-splash
Looks like the redirect/CNAME needs to be updated :)
Fixed. ;)
Thanks for the report.
